Thoughts of a small and very unimportant Debian Developer

At least if you reject as soon as it hits. The “service” currently simply returns a host from NetworkSolutions instead of real information, so all those software rejecting based on the DNS return are currently rejecting legal mail.

If you only use it to score mails a little up and not as a black/white decision you might be lucky, but should still remove it from your lists. Its not the first time that this blacklist sucks like this, seems the people behind it aren’t able to keep it running reliable.
